In the embodiment of Fig. 7, in main conveyer conveyor trunk, arranged at least one valve element 69, this valve element 69 usually along the air blast direction of blowing engine 40 between the blowing engine 40 and feed pipe 103 and/or branch's conveyer conveyor trunk 101,102 of blower unit 4.Blowing engine also produces negative pressure with vacuum generator.
When valve element 64 and 69 when in the closed position, blowing engine 40 makes that the pressure of the part between blowing engine and valve element 69 raises in conveyer conveyor trunk 100.Equally, when advancing against direction of transfer and/or air-flow direction, in the loop feature of the suction side of vacuum generator 3 and/or blowing engine 40 (it comprise in the illustrated embodiment pipe 105,106, separator 20 and main conveyer conveyor trunk 100, from disengagement gear to valve 69 part), when supply station 61,66 when the valve 69,64 and 60,65 of conveyer conveyor trunk cuts out, be mainly negative pressure.
In the embodiment of Fig. 7, branch's conveyer conveyor trunk 102 promptly forms the more part of minor loop from the suction side that on the pressure side extends to main conveyer conveyor trunk of main conveyer conveyor trunk 100.In branch's conveyer conveyor trunk 102, main conveyer conveyor trunk place, end on the pressure side at it is furnished with valve 64, when the valve 64 of branch's conveyer conveyor trunk is opened, and when the valve 69 of main conveyer conveyor trunk cuts out, form littler loop in the illustrated embodiment, wherein, the suction side that on the pressure side by branch conveyer conveyor trunk 102 be circulated to main conveyer conveyor trunk of air from blowing engine 40 from main conveyer conveyor trunk, and further be circulated to pipe 105 and 106 by separator.When vacuum pump unit moved, the on-cycle portion of air was led to outlet 34 in the loop.
In the embodiment of Fig. 7, two first branch's conveyer conveyor trunks 101 are connected in the main conveyer conveyor trunk 100.In the drawings, two supply stations 61 are connected in two first branch's conveyer conveyor trunks 101.Three supply stations 61 are connected in second branch's conveyer conveyor trunk 102 by feed pipe 103.But, they also can be for more, for example 20.They can be opened, and material progressively sends conveyer conveyor trunk to, at first are of the most close separator element, are next hithermost then, or the like.
In the part of the top of figure, also have three supply stations 66 directly to be connected with main conveyer conveyor trunk by feed pipe 104.
Advantageously, in the drawings from the separator unit side, therefore the total suction that is provided to conveyer conveyor trunk 100 by vacuum unit 3 and blower unit 4, is transmitted under the negative pressure and carries out greater than the air blast that is provided by blower unit.By blowing engine 40, can provide for example pressure in 0.1-0.5 crust scope usually.By vacuum generator, also can provide for example negative pressure in 0.1-0.5 crust scope usually.Conveyer conveyor trunk 100, be arranged in the part between blowing engine 40 and the valve 69 (and valve 64), when valve 69,64 cut out, air blast was stored energy (being superpressure), pressure raises simultaneously, for example+0.5 crust.Vacuum unit 3 be pumped in opposite side, promptly provide negative pressure to the separator element 20 (with pipe 105) and the part of valve 69, this negative pressure for example is-0.5 to cling to.When at least one valve 69,64 is opened, difference of pressure even can be 1 crust.Therefore suction provides negative pressure greater than air blast in pipeline, therefore, refuse can be in the funnel suction line of supply station 61.
When aspirating greater than air blast (this is the purpose of system of the present invention), the material (particularly waste materials) of supplying with conveyer conveyor trunk will can not compress and compress, but can " freedom " advance in by the pipeline that transmits the air transmission.Like this, compare greater than the situation in when suction (danger that has the material of transmission will accumulate and stop up conveyer conveyor trunk in this case) with air blast, the material formation possibility of jamming of transmission is obviously lower.And negative pressure has reduced and has transmitted the required power of material, even because also obviously reduce air resistance in the local decompression of the material part correlation of direction of transfer side and transmission.In the drawings, arrow is illustrated in the sense of motion of air in pipeline in the mode of operation.
For example transmit in the waste materials transmitting material, when the material of feed point at first sends conveyer conveyor trunk by suction to by feed pipe 101,103 or 104, can provide acceleration and the transmission that is exceedingly fast to material.
Like this, the delivering power that is provided by difference of pressure for example can be to be in the scope of about 12.32kN (1256kp) in the pipe of 400mm diameter.The diameter of on the pressure side (i.e. the part between blowing engine 40 and valve 69,64 in illustrated example) of conveyer conveyor trunk 100 is can be obviously littler than the diameter of the suction side (promptly being at least the part between valve 69,64 and separator element 20 usually) of conveyer conveyor trunk.Then, form like this on the pressure side can it diameter and cost on more favourable.
In the illustrated embodiment, the suction side at blowing engine in pipe 106 forms accessory 107, in this accessory 107 valve 37 is arranged, and by opening this valve 37, extra air can be delivered to the suction side of blowing engine 4 from the outside in loop.By opening valve 37, can improve the air pressure in the conveyer conveyor trunk when needed, and can improve the transfer rate that transmits material.
This system work usually is as follows: the outlet hatch 21 of separator 20 is closed, and the valve 26 between main conveyer conveyor trunk 100 and separator 20 is opened.Vacuum pump unit 3 and/or blower unit 4 make in winner's conveyer conveyor trunk 100 and keep negative pressure.The suction effect that is provided to conveyer conveyor trunk 100 by disconnector 20 together by vacuum unit 3 and blower unit 4 is greater than the pressure effect that is provided to this conveyer conveyor trunk 100 (promptly to the air blast side, to the part between blowing engine 40 and valve 69 or valve 64) at an end of conveyer conveyor trunk 100 by blower unit 4.
Near feed point (being waste canister) all outlet ports valve 60,65 cuts out.Under the starting situation, the zone valve 64 of branch's conveyer conveyor trunk 102 and the line valve 69 of main conveyer conveyor trunk 100 are closed.
The waste canister that our hypothesis belongs to the feed point 61 in first branch's conveyer conveyor trunk, 101 zones will carry out emptying.Based on the emptying signal, outlet valve 60 is opened for example 2-10 second at once, and therefore, the material of transmission (for example waste materials) is owing to the effect of negative pressure sends branch's conveyer conveyor trunk to, and further sends main conveyer conveyor trunk 100 to.Outlet valve 60 cuts out after the several seconds after initial state usually.Vacuum pump unit 3 keeps required negative pressure, blower unit 4 startings (unless inaccurate received shipment is capable).Therefore valve 69 is opened, and air blast is provided in pipeline, i.e. the pressure effect and the suction effect of Jia Qianging, and this pressure effect and suction effect partly send the material that transmits to separator 20 along pipeline.
When separator 20 is filled, the valve 26 of conveyer conveyor trunk 100 cuts out, and control cock 23 is opened, therefore, the actuator 24 of the outlet hatch 21 of separator is opened this outlet hatch 21, the material that is accumulated in the separator empties in the compactor device 50, and further empties in the waste canister 51.The outlet hatch 21 of separator 20 is closed, and valve 26 is opened.
Then, get back to initial state, repeat evacuation procedure, perhaps can carry out some other feed point/a plurality of feed point of emptying.
Waste canister 51 (for example refuse transfer cask) is replaced when filling or emptying.
In refuse transmits, can optimize wind circulation and air blast, like this, the material part that air blast is always as far as possible closely led and is transmitted.When the material of directly supplying with by feed point 66 partly transmits, at first open the valve 69 in the main conveyer conveyor trunk 100.After material is partly by the point of connection of branch's conveyer conveyor trunk 102 and main conveyer conveyor trunk 100 (in illustrated example), the valve 64 of branch's conveyer conveyor trunk is opened, the valve 69 of main conveyer conveyor trunk cuts out, therefore, the material part that the air blast effect as far as possible closely leads and is transmitted, and the motion that can in conveyer conveyor trunk, keep the material part best.
The embodiment of Fig. 8 has schematically illustrated more massive system, and this system comprises a plurality of minor loop A, B, C, D.This system can comprise a plurality of loops, and valve element A1, B1, C1, D1, AB, CD among pipeline 100A, the 100B that the wind circulation in these loops can be by being arranged in minor loop A, B, C, D, 100C, 100D, 100AB, the 100CD control.Valve A1, the B1 of air blast side like this,, C1, D1 at first close.Blowing engine raise conveyer conveyor trunk or and its bonded assembly pipe and valve A1, B1, C1, D1 between pipe section in pressure.Equally, when advancing against direction of transfer and/or air-flow direction, in the loop feature of the suction side of vacuum generator 3 and/or blowing engine 40 (it comprise in the illustrated embodiment pipe 105,106, separator 20 and conveyer conveyor trunk 100AB, 100CD, from separator 20 to valve A1, B1 and similarly to the part of C1, D1), when the valve 60 of valve A1, B1, C1, D1 and supply station 61 cuts out, be mainly negative pressure.Part loop is wind circulation not, and wind circulation only is controlled at those one or more loops (material transmits from these loops) of system.Usually, at suction side, the valve AB and the CD that lead to minor loop open in initial state, but usually, the valve loop, that will drive stays open, and the valve loop, that do not drive keeps cutting out.
This system comprises piping network, and these piping networks comprise four minor loop A, B, C and D.Each minor loop comprises pipeline 100A, 100B, 100C, 100D, and they can be by opening and closing valve element A1, B1, C1, D1 be connected with pipeline 100 from blowing plant 4 along the loop direction that transmits air from inlet side.In the illustrated embodiment, conveyer conveyor trunk 100A, the 100B of loop A and B are combined as the conveyer conveyor trunk 100AB that leads to separator 20.Same, conveyer conveyor trunk 100C, the 100D of loop C, D is combined as the conveyer conveyor trunk 100CD that leads to separator 20.In illustrated example, arrow is illustrated in the circulation that transmits air under the effective bonded assembly situation in loop in the loop.Same, the material of transmission moves to separator along the direction of arrow from a material feed point of arranging along the loop.
